That is an awkwardly small snippet and not showing any of the real oops state at all (the code/rip dump is actually the user space state at the time of the system call that then causes the problem). Can you make your VM use a bigger terminal so that it shows more of the oops? Assuming your virtual environment supports the usual VESA VGA modes, it might be as easy as just booting with "vga=775" to get a 1280x1024 console. See https://en.wikipedia.org/wiki/VESA_BIOS_Extensions#Linux_video_mode_numbers for more commentary. That *might* work, and get you more of the dump. Linus
